Abstract
An appliance for vacuum packaging and sealing a container, including: a vacuum motor assembly generating suction, a vacuum trough fluidly connected to the vacuum motor assembly, first and second heat sealing elements, and a microprocessor configured to control the vacuum motor assembly and the first and second heating elements in programmable sequences. One programmable sequence may include energizing the vacuum motor assembly to provide suction to the vacuum trough, energizing the first heat sealing element at a first predetermined temperature for a first predetermined time when a first predetermined vacuum level is reached in the vacuum trough, de-energizing the vacuum motor assembly after a third predetermined time has elapsed after the first heat sealing element has been de-energized, delaying a dwell time, and energizing the second heat sealing element at the expiration of the dwell time at a second predetermined temperature for a second predetermined time.
